Diseño de una prótesis de antebrazo de bajo costo

Abstract

This study focuses on the design of a low-cost forearm prosthesis tailored to the Ecuadorian market, where over 15,000 individuals require prosthetic replacements annually. Despite ongoing efforts, access to prostheses remains limited due to bureaucratic hurdles and the high cost of available options. The proposed solution leverages accessible technologies, including 3D printing, to create a functional and affordable prosthesis. The research involved a comparative analysis of various thermoplastics, considering mechanical properties, durability, and cost, to determine the optimal material for the prosthesis. Finite element analysis (FEA) was employed to simulate the structural performance of the prosthesis under realistic load conditions, ensuring both safety and functionality. The findings suggest that PLA is the most suitable material, balancing strength, cost, and ease of manufacturing. This approach demonstrates that it is feasible to produce high-quality, cost-effective prostheses in resource-limited settings.
